The Saints allow a ridiculous 5.1 yards per carry, and the Bills (4.8) aren't much better.

With all of that in mind ...

-- You are starting Buccaneers running back Doug Martin no matter the matchup. Sunday, when the Bucs face the Saints, the electric rookie might be the most enticing play at his position.

-- The Seahawks' Marshawn Lynch (who will play against the Bills this week) and the Chiefs' Jamaal Charles (at the Raiders on Sunday), like Martin, are must-starts. This week, you should dread seeing Lynch (who has four TDs in his last two games) and Charles (399 yards rushing in his last three contests) in your opponent's lineup.

-- The Titans' Chris Johnson, who has rebounded from another dreadful start to have a productive season, has tailed off of late (130 total yards in his last two games and zero TDs in his last three). Monday, when he faces the Jets' 29th-ranked run defense at home, he might be among the top 10 at his position.

-- The Dolphins' Reggie Bush has one TD in his last five contests, but is coming off a decent Week 14, when his 19 touches were his most since Week 5. Bush should be a quality No. 2 running back on Sunday at home against the Jags' No. 31 run defense.

Pass defenses

As we did with the run defenses, we have narrowed the field to five pass defenses you should target each week -- the Buccaneers (312 passing yards allowed per game, 23 TD tosses by the opposition, 92.4 passer rating by opposing QBs), Redskins (289, 27, 90.7), Saints (285, 27, 99.1), Raiders (259, 25, 100.3) and Titans (251, 25, 97.4).

All of which means ...

-- The Saints, who will play host to the Bucs on Sunday, have four must-starts in Drew Brees, Jimmy Graham, Marques Colston and Darren Sproles. Graham (148 yards and zero TDs the last three weeks) and Colston (eight consecutive games with 73 yards or fewer) haven't been great in recent contests, but that should change soon. Another Saints weapon, inconsistent wideout Lance Moore, is a flex option because of the matchup.

-- You're not going to play Brandon Weeden in a fantasy semifinal, even against the Redskins' No. 31 pass defense, but you should start rookie receiver Josh Gordon (14 receptions for 202 yards and a TD in his last two games). A possible desperation play at tight end in deep leagues: the Browns' Benjamin Watson, who has nine catches for 123 yards in his last two contests.

-- Buccaneers QB Josh Freeman hasn't been prolific in his last three games -- a combined 687 yards, four TDs and three interceptions -- but I like his chances Sunday against the Saints' No. 30 pass defense. Bucs receiver Vincent Jackson is an automatic start, and teammate Mike Williams, who has a pair of touchdowns in his last two games, is a decent flex play this week.

-- The Raiders' No. 28 pass defense and the Titans' No. 26 unit won't help you much this weekend, since the teams will be matched up against the Chiefs and Jets, respectively.

Receiver Dwayne Bowe, the only Chief other than Charles who merits starting consideration, is out with a rib injury.

You wouldn't start Jets QB Mark Sanchez in a 20-team league, but you might consider receiver Jeremy Kerley -- the only Jet with more than 317 yards receiving this season.

I repeat: Jeremy Kerley is the only Jet with more than 317 yards receiving this season.
